I have had the same combination for years: Dell/Windows 10/Elements 15 (last 2 months and 10 before that), and have never had such a problem. Elements opens in 8-10 seconds and never freezes. And I always keep it minimized unless for some reason I want to restart the computer. As such, I'm sure there's something wrong with your computer. There are three items to check: processor type, processor speed, and RAM. Old processor types, slow processors, and low RAM can cause the slow launch of Elements (and Lightroom and all other graphic software). However, "locking up" is another story. Also, by slow I mean 1 minute or two and not "forever". I'd recommend have a professional check your computer. Good luck!
